DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A letter packageembodying the present invention generally comprises anenvelope-letterhead blank which has a reply item attached thereto. Theblank includes at least two panels connected together along a commonfold line. One of the panels has copy area thereon and a window openingtherethrough. The reply item is attached to the other of the panels andhas an address area theron which is exposed in the window when said onepanel is folded into overlying relation with said other panel and itsattached reply item. A means is provided for connecting the latter twopanels to form a carrier envelope containing the reply item.

Turning now to the drawing and referring first particularly to FIGS. 1and 2, a two-part letter package embodying the present invention andindicated generally at 10 comprises an envelope-letterhead blank and anassociated reply item respectively generally indicated by the referencenumerals l2 and 14. The blank 12 may take various forms, but preferably,and as shown, it comprises a generally rectangular piece of sheetmaterial which includes two panels 16 and 18 of substantially equal sizeconnected along a transversely extending fold line which, as shown, isdefined by a line of perforation or weakening 20. The panel 18 has copyarea on the front surface thereof, substantially as indicated, forreceiving letter copy or the like which may be imprinted thereon whenthe package 10 is manufactured or at some later time. A window 22 isformed in the panel 16 spaced from the fold line 20. The blank 12 alsoincludes a third panel 24 connected to the panel 16 along another line26 generally parallel to the fold line 20 and which may comprise anotherline of weakening, substantially as shown. The panel 24 has a strip ofadhesive 28 disposed on the front surface thereof, which may, forexample, be of a remoistenable or pressure sensitive type. The panel 24and associated adhesive 28 are provided to secure or seal the two panels16 and 18, in folded connected relation as will be hereinafter furtherdiscussed.

Reply items of various types may be used in practicing the invention. Inthe illustrated case, the reply item comprises a generally rectangularreply card 14 which has an address area 30 on its front surface and may,if desired, have a message, order form or the like imprinted on the rearsurface thereof. The card 14 has a marginal portion 32 separated fromthe remainder thereof by a line of weakening 34. The marginal portion 32is attached to the front surface of the panel 16 by a strip of adhesive36.

After the desired copy has been imprinted in the copy area, the panel 18is folded upwardly along the fold line 20 and into overlying relationwith associated portions of the panel 16 and the reply card 14attachedthereto which brings the window 22 into registry with the address area30. The panel 24 may then be folded downwardly along the fold line 26and into overlying relation with an associated marginal portion of thepanel 18 and sealed thereto by the adhesive strip 28. The name andaddress of a recipient may be imprinted on the address area 30 or, ifdesired, a computer addressed label may be affixed thereto, eitherbefore or after the package is sealed. The various lines of weakeningfacilitate opening of the package 10 and separating the reply item 14therefrom.

The letter packages of the present invention are particularly adaptedfor manufacture and use in continuous form. A typical continuous formletter package assembly embodying the present invention is illustratedin FIG. 3 and designated generally by the reference numeral 40. Theassembly 40 comprises a plurality of individual letter packages 10a, 10asimilar to the letter package 10, previously described, but connectedtogether in end-to-end relation. Parts of each letter package l0a whichare similar to parts of the package 10 bear the same reference numeralsused in the description of the package 10 together with a letter a"suffix. Each letter package 10a includes an envelopeletterhead blank 12aand an associated reply item 14a attached to and carried by the blank12a. The letter packages 10a, 10a are adapted to be separated from eachother after which each. blank 12a may be folded and joined or sealed toform a carrier envelope which contains an associated reply item 14a.

The assembly 40 is formed from an elongated web of sheet materialdesignated generally by the numeral 42 which defines a longitudinalseries of connected separable envelope-letterhead blanks 12a, 12asimilar to the blanks 12, 12 previously described. The reply items 140,14a are substantially identical to the reply item 14 and formed from aplurality of separate pieces of sheet material and attached inlongitudinal series along the web 42.

Further considering the assembly 40, each blank 12a is connected to thenext successive blank 12a in the series by a longitudinally extendingline of weakening 44 formed on the web 42. The blanks which comprise theassembly may be further connected by at least one longitudinallyextending marginal carrier strip. The illustrated embodiment 40 includesa pair of carrier strips 46, 46. Each carrier strip 46 is separated fromthe remainder of the web by a longitudinally extending line of weakening48 transversely spaced from an associated side edge of the web 42. Alongitudinal series of configurations or holes 50, 50 are formed in eachcarrier strip 46 for engaging a sprocket, pin wheel feed mechanism orthe like of an associated computer printer or other printing apparatus.

The essential difference between the letter packages a, 10a and theletter package 10 previously described resides in the arrangement of thecopy area on the envelope-letterhead blank and the location of thetipped-on reply or return vehicle attached thereto. Further consideringa typical letter package 10a, as shown in FIG. 3, the blank 120comprises two panels 16a and 18a connected together along a common foldline 20a defined by a line of weakening formed on the web 42. The blank12a also includes a third panel 24a connected to the lower edge'of thepanel 16a along another line defined by a transversely extending line ofweakening 260 formed on the web. As in the previously describedembodiment, the panel 18a has a window 22a opening therethrough andspaced from the fold line 20a. A strip of adhesive 28a disposed on thefront surface of the panel 24a extends transversely thereof for sealingthe package 10a after separation from the assembly 40. The reply item14a is attached to the panel 160 by a strip of adhesive 360 aspreviously discussed.

After the desired letter or other copy has been imprinted on theenvelope-letterhead blanks 12a, 12a, the letter packages 10a, 10a may beseparated from each other for folding and sealing. The carrier strips46, 46 are removed from the assembly 40 by bursting or tearing along thelines of weakening 48, 48. Each package 100, 10a is separated fromadjacent packages in the series by bursting or tearing along the linesof weakening 42, 42. When the letter copy is of a personalized computerprinted type, the letters are preferably printed and the reply itemsaddressed in the same computerized printing operation thereby whollyeliminating the need for any collating operation. However, if desired,each letter package 10a may be addressed after it has been folded andsealed, as previously discussed.

Referring now to FIGS. 4 and 5, another continuous form assembly ofletter packages embodying the invention is designated generally at 40b.The assembly 40b is formed in part from an elongated web of sheetmaterial 42b and comprises a plurality of series of connected letterpackages 10b, 10b. The letter packages in each series are connected inside-by-side relation to the letter packages in another series. In theillustrated embodiment 40b two series are shown and designated S1 andS2, however, assemblies which include additional series arecontemplated. The letter packages in each longitudinal series areconnected to those in an adjacent series along a longitudinallyextending line of weakening such as indicated at 52. The assembly 40bcomprises a pair of marginal carrier strips 46b, 46b and a plurality ofseries of envelope-letterhead blanks 12b, [212 formed on the web 42b.Each blank 12b is substantially identical to the blank 12a previouslydescribed and carries a reply item 54. Parts identical to partspreviously described bear the same reference numeral and a letter bsuffix and will not be hereinafter further described.

' Considering now a typical reply item 54in further detail, andreferring particularly to FIG. 6, the reply item comprises an envelopestructure which includes a plurality of connected panels. Morespecifically, the reply envelope structure 54 is formed from a singlepiece of sheet material and includes an envelope indicated generally at56 and a panel or coupon 58 attached to the envelope 56. The envelopehas a plurality of integrally connected envelope panels whichincludebody panels 60 and 62 connected along a lower fold line 64. A pair ofside panels 66, 66 connected to the side edges-of the body panel 60along fold lines 68, 68 are folded inwardly and further connected to thebody panel 62 by strips of adhesive 70, 70. A closure panel 72 isconnected to the upper edge of the body panel 60 along another fold lineand carries a strip of sealing adhesive 74. The panel 58 is connected tothe upper edge of the body panel 62 along another fold line 76 definedby a line of weakening. A pair of tabs 78, 78 extend outwardly fromopposite ends of the panel 58 for attaching the envelope structure 56 toan associated envelopeletterhead blank 12b. Each tab 78 is separatedfrom the panel 58 by an associated line of weakening 80. The tabs 78, 78are attached to the front surface of the blank 12b, 12b by strips ofadhesive 82, 82. The panel 58 has an address area 30b on the frontsurface thereof. as shown in FIG. 4, for registry with an associatedwindow 22b, and may have an order form or other copy imprinted on itsrear surface.

When the letter packages 10b, 10b are ready to be folded and sealed, thecarrier strips 46b, 46b are torn or burst along the lines of weakening48b, 48b and the letter packages are further separated from each otherby tearing or bursting along the various lines of weakening 44b and S2.The remaining lines of weakening on each letter package are provided tofacilitate the opening and separation of the various parts of thepackage by a recipient thereof.
